FEATURES
NIGHTTIME AIRFLOW CONTROL
The Nighttime Airflow Control option is an energy saving feature where the thermostat uses the temperature sensor
in the bedroom area to control heating and cooling calls and directs more airflow to the bedroom at night
and less airflow to the unoccupied living . Nighttime Airflow Control begins at 10:00pm but can be changed
by accessing the schedule in the User Options. The airflow to the bedroom space defaults to 130% but can be
adjusted for both heating and cooling in the User Options. Nighttime Airflow Control is defaulted to On but can be
turned Off in the User Options. The homeowner should consider turning this option off if bedrooms are located on
the same floor as the living area and using the same airflow trunk as the living area.

AUTOMATIC OR MANUAL AIRFLOW CONTROL
Automatic Airflow Control is the thermostat default and is typically used by homeowners to maintain uniform
comfort throughout the home. However, homeowners with unusual work schedules, home offices, etc. may want to
use the manual airflow control feature. This features allows the homeowner to change the airflow level as desired
and hold that level indefinitely. This feature needs to be enabled using Installer Option 18. The homeowner then
needs to turn automatic airflow control off using the User Options. The Nighttime Airflow Control option is still
enabled but can be turned off, if desired, using the User Options.
AIRFLOW OVERRIDE
DISPLAYING THE LIVING AND BEDROOM AREA TEMPERATURE
The living area temperature is normally displayed. The bedroom area temperature can be displayed by touching
Living on the touchscreen. The temperature will change to the bedroom space temperature, indicated by Sleeping.
Touch Sleeping to return to displaying the Living area temperature.
On occasion, homeowners may want to direct more airflow to an area. For example, during a party, more airflow
may be desired in the living area. The homeowner sets the airflow level to the area and the thermostat will hold
the airflow for 3 hours. After 3 hours, the thermostat returns to automatic airflow control.
Features
AIRFLOW CONTROL TURNED OFF
In some installations, the EvenAir thermostat has been installed to control the system only. The thermostat operates
just like any other thermostat. The airflow control options are disabled and airflow is no longer displayed on the
thermostat.

DAMPER OPERATION
Problem - No airflow to the sleeping area AND living
area registers
Turn system off immediately. Both dampers may be wired
backwards at the subbase or at the damper actuator (closing
rather than opening).
Problem - No airflow to the sleeping area OR living
area registers
Turn system off. One of the dampers may be wired backwards
at the subbase or at the damper actuator (closing rather
than opening).
Problem - When directing airflow to the sleeping area, the
airflow is actually directed to the living area, and when
directing the airflow to the living area, the airflow is actually
directed to the sleeping area.
Turn system off. Check if the dampers are switched (sleeping
area damper is wired to the living area terminals and the
living area damper is wired to the sleeping area terminals.)
SENSOR INSTALLATION
Problem - nS message on thermostat.
Check that the sensor is wired correctly. Check for a short in
the sensor wiring.
Problem - Sleeping area temperature reading very high or
very low.
Check that the correct sensor(s) have been used. One TS51
sensor is used in a single sensor installation. Two TS52
sensors are used in a dual sensor installation.
COMFORT CONCERNS
Problem - Downstairs bedroom is too cold or too hot at night.
The Nighttime Airflow Control option directs more airflow to the
sleeping area and less airflow to the unoccupied living area. If
the downstairs bedroom is on the same HVAC trunk as the
living area, the downstairs bedroom may become uncomfortable
at night. Turn off the Nighttime Airflow Control option using the
User Options.
Problem - The room temperature on the thermostat seems
too high or too low.
The thermostat is factory calibrated within 1 degree.
However, if a homeowner finds the temperature “feels”
too high or too low, the thermostat can be calibrated to
what the homeowner feels is the correct temperature using
Installer option 13 for the living area and option 14 for
the sleeping area.
